PRC Component
This is a type of matrix component that is controlled using the PESA
Routing Control (PRC) protocol. The component resides within the
address space defined within the PRC protocol. Matrices using the PRC
protocol include the Cougar and Jaguar families of matrices.
Protect
A property placed on a destination that prevents all users from taking a
switch on the destination except for the requester that initiated the protect.
Protects may be cleared by the requester that initiated the protect, a
requester of a higher lock/protect priority, or a master requester.
Readback
The status read back from an actual matrix by the control system. A
readback error occurs when the value read back from the matrix for a
specified physical output is not the value expected by the controller.
Reentry
A virtual router path that allows a single switch specification to take a
source to a number of destinations at the same time. A reentry is named
as well as assigned source and destination numbers. A reentry is treated
as a source and/or destination by user panels and the CPU link. A reentry
is virtual in that it is performed in software and does not require any more
additional physical crosspoints than any other path.
